iM'PRovEMENT IN cow-MILKERS.

.Specification forming part of Letters Patent No. 154,811, datedSeptember 8, 1874 application filed July 24,1874.

To all whom it may concern:

Be it known that we, JOHN MARTIN STAN- LEY and HENRY JAMEs, ofSheffield, York county, England, have invented certain Improvements inAppliances for Milking Cows, of which the following is a speciiication:

Our present invention has for its object im-.,

provements in the present appliance for milking cows, which will savetime and labor, and secure a more cleanly process of milking.

In order that our said invention maybe more clearly and more fullyunderstood, and l be .more readily performed, we now proceed to explainthe same, with the aid of the accompanying drawing, which forms part ofthis elevation ofa similar apparatus fitted in the neck of a milkcan.Fig. 3 is a full-size elevation of a small iiexible tube, and itsmetallic tube for insertion in the cows teat, which metallic tube ishereinafter called the insertion-tube,77 also showing our improvedelastic bands and loop for holding the saidinsertiontube in place duringthe milking process. Fig. 4 is a full-size view of the lower end of thesaid small flexible tube, showing a short metallic tube or lining ttedtherein.

lIn carrying our present invention into practice, we propose to useflexible tubes a, with metallic insertion-tubes b. The four ilexibletubes a are inserted and secured in one end of a larger tube, having aninternal-cavity or common channel large enough to receive therein, andconvey to the milk-pail cor can d, (hereinaftercalled receivingvessels,)the four streams of milk from the four teats of the cow through the fourilexible tubes a. This Y common. channel may be made of any suitablematerial, either flexible or rigid, or partly of each, and be arrangedto slide in the neck h2 h3 of the receiving-vessel. The lower part f ofthe said common channel (shown in Fig.1) is formed of metal, and inwhich part f the Asliding the lower or upper part g, made of vulcanizedcaoutchouc, slides. The common channel f (shown in Fig. 2) is wholly ofvulcanized caoutchouc in one tube, the lower end of which slides in theneck h3 of the milk-can d, and is provided with a free elastic ring, i,fitting sufficiently tight to support the tube ff, and prevent itssliding down in the neck of the receiving-vesselfbelow the point atwhich it is fixed or placed.

To prevent dirt or other impurities from passing into thereceiving-vessels during the process of milking, we iit such vesselswith a top, h h1, or a movable lid or cover, by preference in the formof a dome, which top or cover has, in or near its center, a neck,socket, or nozzle, h2 h3, in which the lower end of the common channelslides; or the top or cover may be tted with two necks, sockets, ornozzles, to receive a common channel from two cows at the same time, sothatthe milk passes from the cow or cows to the receiving-vessel withoutexposure, and consequently free from admixture with any foreign matterwhatever. The common channel (shown at f g, Fig. l) is lengthened orshortened, at pleasure, by metallic tube f in the neck h1 of the top orcover h of the receiving-vessel, and fixing such tube f at the requireddistance or length by a set-screw, fi, fitted in or to the neck h ofsuch top or In order to prevent the insertion-tubes b from sliding ordropping out of the teats of the'cow by any motion of the latter, orotherwise, during the process of milking, we secure the saidinsertion-tubes in or to the teats by means of elastic bands or cords j,one end of which is attached to the root or lower part Y of suchinsertion-tubes, and having attached to their upper parts or ends anelastic loop or circular band or cord, 7o, of a suitable size-andstrength to grasp the teat with just sufcient pressure to hold theinsertion-tubes bin place. Our improved apparatus is self-acting afterybeing attached to the cow, and the milking process occupies less timethan usual, especially when two cows are milked into the samereceiving-vessel at the same time.

Having thus fully described the nature of our said invention, and themethod of performing the saine, We wish it to be understood or cords,substantially as herein described and that we do not claim the flexibletubes a, nor shown.

the insertion-tubes b, per so; but JOHN MARTIN STANLEY.

We claim as our invention, and desire to se- HENRY J AMES. eure byLetters Patent- Vitnesses:
